For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0025] refer to Figures 1 to 8 An embodiment of the present application provides an automatic preparation device for pipeline welding grooves, including: a platform 100 and a groove processing mechanism 200 and a pipeline conveying mechanism 300 arranged on the platform 100.

[0026] The groove processing mechanism 200 includes a fixed ring 201 and a movable ring 202. The fixed ring 201 is equipped with a fixing assembly for coaxially securing the fixed ring 201 with the pipe 1 to be processed. The movable ring 202 is coaxially and rotationally connected to the fixed ring 201. The movable ring 202 is equipped with a cutting assembly, which includes a cutter head 203. The cutter head 203 is used to cut the pipe 1 to be processed to form a groove when the movable ring 202 rotates relative to the fixed ring 201. The cutter head 203 can move radially along the movable ring 202 to adjust the cutting distance of the cutter head 203.

[0027] The pipe conveying mechanism 300 includes a chute 301, multiple sliding wheels 302, and multiple drive wheels 303. The chute 301 is mounted on the platform 100, with the axial direction of the chute 301 aligned with the axial direction of the retaining ring 201. The sliding wheels 302 are positioned on either side of the inner wall of the chute 301 and are used to support the pipe 1 to be processed. The drive wheels 303 are mounted on the platform 100 and are configured to rotate to drive the pipe 1 to be processed axially within the chute 301. The drive wheels 303 and sliding wheels 302 form a support track, and both can move radially along the retaining ring 201 to adjust the support track.

[0028] The automatic pipe welding groove preparation device of the present embodiment includes a groove processing mechanism 200 and a pipe conveying mechanism 300. The pipe conveying mechanism 300 can transport the pipe 1 to be processed to the processing location, and the groove processing mechanism 200 can form a groove on the pipe 1 transported to the processing location. In other words, the device can realize loading and unloading of the pipe 1 to be processed and groove processing.

[0029] Furthermore, because the cutter head 203 can move radially along the movable ring 202, the cutting amount of the cutter head 203 can be adjusted by moving the cutter head 203, thereby adapting the process to processing pipes of varying diameters. Because both the driving wheel 303 and the sliding wheel 302 can move radially along the fixed ring 201, the support path can be adjusted by moving the driving wheel 303 and the sliding wheel 302, thereby enabling the pipe conveying mechanism 300 to maintain the axial position of pipes of varying diameters while conveying them. This allows the groove processing mechanism 200 to process pipes of varying diameters without changing its own position.

[0030] In some examples, the fixed ring 201 and the movable ring 202 are both circular rings, and the fixed ring 201 is sleeved outside the movable ring 202. This can limit the radial deviation of the movable ring 202 during rotation to ensure the cutting effect. This embodiment of the present application does not make specific limitations on this.

[0031] In some examples, the fixed ring 201 is provided with a rotating gear 204 and a rotating motor 205. The rotating gear 204 extends through the fixed ring 201, and the rotating motor 205 is connected to the rotating gear 204 and is used to drive the rotating gear 204 to rotate circumferentially. The outer surface of the movable ring 202 is provided with gear teeth 206, which mesh with the rotating gear 204. During use, the rotating motor 205 can drive the rotating gear 204 to rotate circumferentially, thereby driving the movable ring 202 to rotate circumferentially relative to the fixed ring 201. This enables the movable ring 202 to rotate relative to the fixed ring 201, thereby driving the cutter head 203 to cut the pipe 1 to be processed to form a groove. This embodiment of the present application does not specifically limit this.

[0032] In some examples, the fixing assembly includes multiple radial push rods 207, which are disposed on the end surface of the fixing ring 201 and spaced apart along the circumference of the fixing ring 201. The radial push rods 207 are configured to extend and retract radially along the fixing ring 201 to clamp and secure the pipe 1 to be processed. In specific configurations, the radial push rods 207 can be pneumatic push rods, electric push rods, etc., and their extension rods can extend and retract radially along the fixing ring 201, thereby clamping or releasing the pipe 1 to be processed. This embodiment of the present application does not impose any specific limitations on this.

[0033] In some examples, the fixing assembly further includes a plurality of arc-shaped clamping plates 208, each of which is disposed on a plurality of radial push rods 207. Specifically, each arc-shaped clamping plate 208 is disposed at the front end of the telescopic rod of a corresponding radial push rod 207. When the radial push rod 207 extends and retracts its telescopic rod along the radial direction of the fixing ring 201, the arc-shaped clamping plates 208 can clamp the pipe 1 to be processed, thereby increasing the contact area and improving the fixing effect. This is not specifically limited in the present embodiment.

[0034] In some examples, the cutting assembly further includes a moving unit, on which the cutter head 203 is disposed, and which can drive the cutter head 203 to move radially along the movable ring 202 when the moving unit is started. Specifically, the moving unit includes a fixed frame 209, a screw rod 210, a slider 211, and a first motor 212. The fixed frame 209 is a rectangular frame, and the fixed frame 209 is disposed on the end face of the movable ring 202. The screw rod 210 is rotatably disposed on the fixed frame 209 and extends radially along the movable ring 202. The slider 211 is slidably disposed on the fixed frame 209 and is threadedly engaged with the screw rod 210, and the cutter head 203 is disposed on the slider 211. The first motor 212 is disposed on the fixed frame 209 and is connected to the screw rod 210. During use, the first motor 212 can drive the screw rod 210 to rotate circumferentially. When the screw rod 210 rotates circumferentially, the slider 211 moves axially along the screw rod 210, thereby driving the cutter head 203 to move axially along the screw rod 210 (or radially along the movable ring 202). This embodiment of the present application does not specifically limit this.

[0035] In some examples, the cutting assembly further includes a rotating unit, which is disposed on the slider 211. The cutter head 203 is disposed on the rotating unit and indirectly disposed on the slider 211. When the rotating unit is activated, it can drive the cutter head 203 to rotate relative to the movable ring 202 to adjust the angle of the cutter head 203, thereby being suitable for cutting grooves of different angles on the pipe. Specifically, the rotating unit includes a mounting bracket 213, a rotating shaft, and a second motor 214. The mounting bracket 213 has a U-shaped structure and is disposed on the slider 211. The rotating shaft is rotatably disposed on the mounting bracket 213, and the cutter head 203 is disposed on the rotating shaft. The second motor 214 is disposed on the mounting bracket 213 and connected to the rotating shaft. During use, the second motor 214 can drive the rotary shaft to rotate circumferentially, and when the rotating shaft rotates, it can drive the cutter head 203 to rotate relative to the movable ring 202. This embodiment of the present application does not specifically limit this.

[0036] In some examples, the groove processing mechanism 200 is disposed in the chute 301 and fixedly connected to the chute 301. This arrangement allows the groove processing of the pipe 1 to be processed without having to move it out of the chute 301. Compared with the method of processing the pipe 1 after it is moved out of the chute 301, this can reduce the moving distance of the pipe 1 to be processed and improve the processing efficiency.

[0037] In some examples, the retaining ring 201 is provided with a mounting assembly, which is used to mount the retaining ring 201 to the chute 301. Specifically, mounting assemblies are provided on radially opposite sides of the retaining ring 201, each comprising a mounting seat 215 and a screw 216 disposed on the mounting seat 215. During installation, the mounting seat 215 is placed on the upper edge of the chute 301, and the screw 216 is screwed into the chute 301 to securely connect the retaining ring 201 to the chute 301, thereby securing the groove processing mechanism 200 to the chute 301. This embodiment of the present application does not impose any specific limitations on this.

[0038] In some examples, the fixing ring 201 can be moved axially along the slide groove 301 to move the fixing ring 201 to the installation position. In a specific configuration, the mounting base 215 is provided with a roller 217, which is located between the mounting base 215 and the slide groove 301 to facilitate movement of the fixing ring 201. Furthermore, to prevent the screw 216 from contacting the slide groove 301 during movement and causing friction, a stopper can be provided between the screw 216 and the mounting base 215 to prevent the screw 216 from approaching the slide groove 301 on its own. For example, the limiting unit includes a limiting frame 218, a supporting piece 219, and a spring member 220. The limiting frame 218 is sleeved outside the screw rod 216 and mounted on the upper surface of the mounting seat 215. A limiting space is formed between the limiting frame 218 and the mounting seat 215. The supporting piece 219 is located in the limiting space and is fixedly connected to the screw rod 216. The spring member 220 is sleeved outside the screw rod 216 and is located between the supporting piece 219 and the mounting seat 215. When the screw thread is not screwed into the mounting seat 215, the spring member 220 can exert an elastic force on the supporting piece 219, causing it to drive the screw rod 216 to move away from the mounting seat 215, thereby preventing the screw rod 216 from contacting the slide groove 301 and generating friction, which would affect the movement of the fixing ring 201.

[0039] In some examples, the inner surface of the chute 301 is curved, and the chute 301 is formed by two inclined and symmetrically arranged curved support plates. In a specific configuration, a conveyor rail 304 is provided on the platform 100, and the curved support plates are mounted on the conveyor rail 304 to maintain the tilt. This embodiment shows a gap between the two curved support plates.

[0040] In some examples, the surface of the driving wheel 303 is provided with an anti-slip structure 305 to increase the friction between the driving wheel 303 and the pipe 1 to be processed. In a specific configuration, the surface of the driving wheel 303 can be provided with an anti-slip rubber strip. This embodiment of the present application does not specifically limit this.

[0041] In some examples, the pipeline conveying mechanism 300 further includes a plurality of curved support plates 306, each of which is disposed on either side of the inner wall of the chute 301. A plurality of sliding wheels 302 are rotatably disposed on each of the curved support plates 306. In a specific configuration, one or more sliding wheels 302 may be disposed on each curved support plate 306. This embodiment shows that each curved support plate 306 is provided with two sliding wheels 302, which are arranged circumferentially along the chute 301.

[0042] In some examples, the pipeline conveying mechanism 300 further includes a plurality of first push rods 307, each of which is disposed on both sides of the inner wall of the chute 301 and is connected to a plurality of curved support plates 306. In a specific configuration, the first push rods 307 can be pneumatic push rods, electric push rods, etc. The first push rods 307 are disposed on the inner side of the chute 301, and the telescopic rods of the first push rods 307 are connected to corresponding curved support plates 306. The first push rods 307 can extend and retract their telescopic rods along the radial direction of the fixing ring 201 to drive the curved support plates 306 and the sliding wheels 302 thereon to move along the radial direction of the fixing ring 201.

[0043] In some examples, the pipe conveying mechanism 300 further includes a support strip 308, which is positioned below the chute 301 (between the two conveying rails 304). The support strip 308 has a first side and a second side that oppose each other. The plurality of drive wheels 303 are rotatably mounted on the first side of the support strip 308. In a specific configuration, the support strip 308 is provided with a plurality of U-shaped seats 309, and the plurality of drive wheels 303 are rotatably mounted on the plurality of U-shaped seats 309. In this context, the first side and the second side are the upper and lower surfaces of the support strip 308, respectively.

[0044] In some examples, the pipeline conveying mechanism 300 further includes a conveying motor 310 and a transmission mechanism, wherein the transmission mechanism connects the multiple drive wheels 303, and the conveying motor 310 is connected to the transmission mechanism. In a specific configuration, the transmission mechanism can be a gear chain 312 transmission mechanism. For example, the gear chain 312 transmission mechanism includes multiple gear plates 311 and chains 312, each gear plate 311 is respectively disposed on each U-shaped seat 309, and each gear plate 311 is respectively connected to each drive wheel 303. The chain 312 is wound around the multiple gears. When the conveying motor 310 drives any gear plate 311 to rotate, the chain 312 can drive all gear plates 311 to rotate, thereby driving all drive wheels 303 to rotate. This embodiment of the present application does not specifically limit this.

[0045] In some examples, the pipe conveying mechanism 300 further includes a plurality of second push rods 313, each of which is disposed on the platform 100 and is connected to the second side of the support strip 308. Specifically, the second push rods 313 can be pneumatic push rods, electric push rods, etc., with telescopic rods of the second push rods 313 connected to the back side of the support strip 308. The second push rods 313 can extend and retract their telescopic rods radially along the fixing ring 201 to drive the support strip 308 and the drive wheel 303 thereon to move radially along the fixing ring 201.

[0046] In some examples, the automatic pipe welding groove preparation device further includes a debris cleaning mechanism 400 for removing debris generated during processing. This prevents metal debris from accumulating on the pipe 1 to be processed and the groove processing mechanism 200, helping to ensure equipment cleanliness and improve processing quality.

[0047] In some examples, the debris cleaning mechanism 400 includes an air blowing assembly and a collection box 407. The air blowing assembly is used to blow air toward the processing location of the pipe 1 to be processed to remove debris. The collection box 407 is disposed on the platform 100 and below the groove processing mechanism 200 to collect the blown-off debris. During use, the debris cleaning mechanism 400 uses the air blowing assembly to blow away metal debris, causing the metal debris to fall into the collection box 407, thereby cleaning the automatic pipe weld groove preparation device.

[0048] In some embodiments, the blowing assembly includes a gas tank 401, a nozzle 402, and an air pipe. The gas tank 401 is used to store compressed gas. One end of the air pipe is connected to the gas tank 401, and the other end is connected to the nozzle 402. During use, the gas tank 401 delivers compressed gas through the air pipe, and the compressed gas is finally ejected through the nozzle 402. In a specific configuration, the blowing assembly may also include an air compressor 406, which is connected to the gas tank 401. During use, the air molding machine can fill the gas tank 401 with compressed gas.

[0049] In some examples, the blowing direction of the air blowing assembly is adjustable, that is, the direction of the nozzle 402 is adjustable. Specifically, the air pipe includes a first air pipe 403 and a second air pipe 404. The first air pipe 403 and the second air pipe 404 are angled (e.g., 90°) with each other and connected by a rotating connecting shaft 405. During use, by rotating the first air pipe 403 relative to the second air pipe 404, the angle of the nozzle 402 can be changed, thereby changing the blowing direction of the air blowing assembly.

[0050] In some examples, the collection box 407 is provided with a baffle 408, which is located on the side of the groove processing mechanism 200 away from the nozzle 402. The baffle 408 is used to intercept debris and make it fall into the collection box 407. In this embodiment, the baffle 408 and the nozzle 402 can be located on both sides of the fixing ring 201 in the axial direction.

[0051] In some examples, the collection box 407 is movable relative to the platform 100 and has a debris collection position and a debris removal position relative to the platform 100. Specifically, when in the debris collection position, the collection box 407 is used to collect blown-off metal debris, and when in the debris removal position, an operator or automated equipment can remove the metal debris from the collection box 407 for recycling.

[0052] In some examples, a moving wheel 409 is provided at the bottom of the collection box 407. This makes it easier to move the collection box 407.

[0053] In some examples, the platform 100 is provided with a positioning groove 101, and the moving wheels 409 of the collection box 407 are located in the positioning groove 101. In other words, when the collection box 407 moves, the positioning groove 101 can position the moving wheels 409 of the collection box 407, preventing the collection box 407 from deviating from the debris collection position and the debris removal position.

[0054] In some examples, the platform 100 is provided with a limit assembly, which is used to limit the movement of the collection box 407 relative to the platform 100. Specifically, the limit assembly includes a telescopic cylinder 102 and a limit block 103. The telescopic cylinder 102 is mounted on the platform 100, and the limit block 103 is mounted on the telescopic rod of the telescopic cylinder 102. The limit block 103 is used to move into the movement trajectory of the moving wheel 409 when the telescopic cylinder 102 extends and retracts its telescopic rod, thereby limiting the movement of the collection box 407.
